Benefits of technology
The present invention relates to a lighting control apparatus which uses a wire and wireless integrated dimming circuit that is capable of removing noise from the input power and apply it to the converter. The apparatus includes an EMI filter for the input power, an input filter module for removing noise from the wired dimming signal, an output filter module for removing noise from the wired dimming signal, and a first diode for preventing reverse bias voltage. Additionally, a second diode is included in the wireless module for preventing reverse bias voltage. This invention improves the quality and stability of the lighting control apparatus, ensuring the efficient and reliable operation of the dimming circuit.
Problems solved by technology
In addition, since the conventionally used wired dimming circuit 160 adopts a complicated circuit using an OP-AMP, there is a problem in that high price and high volume are enforced due to the configuration of the circuit.
